Reinforcing ribs for rotomolded parts help keep nominal wall thickness to a minimum. That’s important because thicker walls in plastic parts can increase cycle times and add material costs. https://t.co/rK6skmVV8a #rotomolding #rotomolder #rotationalmolding #designtips

Four of the most common rotational molding materials are LLDPE, HDPE, PP, and static-dissipative PE. Each has different properties, so what's the right choice for your project? https://t.co/5UhLclwNOv #rotomolding #rotomolder #rotationalmolding #plastics

Looking for lightweighting? 🪶Rotomolded parts are replacing cast or machined metal components in many industrial applications. Examples include plastic manifolds, mufflers, and tanks. 👏https://t.co/2qE2Qkk51M #lightweighting #manifolds #mufflers #tanks

[Gregstrom Corp. @GregstromCorp]

Rotational molding and injection molding can both produce enclosures. 🗳️Rotomolding uses lower-cost tooling and can create shapes and features that other plastics processes can't match. ⚙️https://t.co/GyZtt6IY15 #rotationalmolding #injectionmolding #enclosures #plastics

Six-axis robotic routing for rotomolded parts cuts thick sheets cleanly and can handle 3D parts. 🤖It can also process more parts per hour than CNC equipment. ✔️ https://t.co/KrbyPundeF #roboticrouting #partsfinishing #rotationalmolding #rotomolding

[Gregstrom Corp. @GregstromCorp]

Five-axis CNC routing for rotomolded parts supports complex designs and smooth surface finishes. 💡It also produces compound radii on plastic surfaces. 👍https://t.co/KrbyPundeF #cncrouting #partsfinishing #rotationalmolding #rotomolding

[Gregstrom Corp. @GregstromCorp]

Uniform wall thicknesses are easier to achieve with rotational molding than other plastics processes. ✅The molds are less expensive, too. https://t.co/XgqvEokD16 #rotationalmolding #blowmolding #injectionmolding
